1. A FUNCTION DEVICE FOR ENABLING THE PRODUCTION OF A CURRENT FLOW WHICH IS PROPORTIONAL TO A PREDETERMINED EXPONENTIAL OF AN INPUT VOLTAGE WITH LESS THAN A PREDETERMINED PERCENTAGE ERROR, FOR INPUT VOLTAGES OF UP TO A PREDETERMINED MAXIMUM TOTAL VOLTAGE COMPRISING: A PLURALITY OF AT LEAST FOUR VARISTOR ELEMENTS CONNECTED IN SERIES, EACH ELEMENT CHARACTERIZED BY A CAPABILITY, WHEN CONNECTED IN SERIES WITH A LINEAR RESISTOR, OF ENABLING CURRENT FLOW THROUGH SAID ELEMENT WHICH VARIES ACCORDING TO SAID PREDETERMINED EXPONENTIAL FOR VOLTAGES ACROSS THE ELEMENT AND RESISTOR OF UP TO A PARTICULAR PARTIAL VOLTAGE WITH LESS THAN APPROXIMATELY IN SAID PREDETERMINED PERCENTAGE ERROR, THE SUM OF SAID PARTIAL VOLTAGES OF SAID ELEMENTS BEING APPROXIMATELY EQUAL TO SAID PREDETERMINED MAXIMUM TOTAL VOLTAGE.
